Abstract: A variable interference anvil and knife combination is provided to selectively sever elastics in a laminate and preferably not sever the nonwoven portions of the laminate. The distance between the anvil and the knife can be programmatically altered to provide for smaller or larger gaps as processing speeds are changed.

Abstract: An object of the present invention is to provide an electric actuator having a structure capable of reducing an external force or impact acting on a screw shaft when a piston rod is at a stretched position. An electric actuator includes a nut, a piston rod, recesses, keys, holes, and a tapered portion. Into the nut, a screw shaft is screwed. The piston rod moves linearly via the nut. The recesses are formed on an outer circumferential surface of the nut. The keys are each provided to a recess. The tapered portion is formed on an inner wall of the cylinder body. The piston rod advances to move the keys outward to cause the keys to fit to the tapered portion to block retraction of the piston rod.

Abstract: A tape measure that incorporates a marking device for allowing an individual to measure and mark a wide variety of materials in a more efficient and economical manner, and for measuring and marking the beginning point of reference and the measured position point simultaneously. The tape measure has a housing, a coiled measuring tape, a tape tip, and a marker having a marking wheel mounted on an axle. The marking wheel having a belt configured for transferring a powdered marking substance, such as chalk, to the surface to be measured and marked.

Abstract: A measuring and marking apparatus for firewood includes an upstanding tubular body having a handle, defining a channel to carry an inverted aerosol can of marking material and journaling a measuring wheel having a circumferential length equal to a desired length of firewood. The measuring wheel is journaled between wheel forks carried by and extending from the lower body portion. A protruding dog carried on a face of the measuring wheel engages an actuator carried by the body and communicating with the nozzle of the aerosol can so that each rotation of the measuring wheel causes a dispersal of marking material onto the surface being measured and marked.

Abstract: A vial having an outer wall which is straight and cylindrical and a curved inner cavity. The inner cavity is curved in a substantially uniform arc. The apex of the curved cavity is closer to the cylindrical outer wall of the vial than the ends of the inner cavity. The inner cavity is substantially uniform in cross section throughout its length.

Abstract: Whether a previously computed valve command value Y−1 is within a neutral zone ±&agr; is determine. If the determination result is “Yes”, processing to compute a valve command value for a neutral dead zone is executed. If the determination result is “No”, processing to compute a valve command value for a driving zone is executed. In the latter case, by using a valve command value X and the previously computed valve command value Y−1, it is determined in which one of acceleration, deceleration/stop, and lever-reversed condition is the operating status, and a maximum setting rate in one of acceleration, deceleration/stop, and lever-reversed condition is computed from a corresponding function &Dgr;Y=fmax1(X), etc. Then, a control signal is computed while restraining a change rate of the operational signal to be kept not more than the computed maximum change rate, and a flow control valve 3 is controlled in accordance with the computed control signal.

Abstract: Rolls of printer paper are marked with information which indicates the length of paper remaining on a roll by measuring the distance between indicia successively applied by two separate print drums which each apply indicia at substantially equally spaced first and second intervals, respectively. The length of paper remaining on the roll is determinable by measuring the spacing between indicia applied by each drum. Some of the applied indicia may also be bar-coded with roll length indicia which includes a second means of determining length of paper remaining on a print roll and other information such as paper type, total roll length and name of the manufacturer. The indicia can be applied at speeds of paper travel substantially higher than the fastest known dynamic printing techniques.

Abstract: An apparatus for marking a cloth or other material for the precise placement of stitches in a quilt. The apparatus includes a handle portion having extended therefrom a stem or elongated bar which includes a means for containing a marking medium such as ink or chalk and a wheel rotatably connected to the end of the stem, the wheel having a series of spaced points thereon, the points communicating with the marking medium such that as the wheel is rolled across the cloth the spaced pointed portions of the wheel mark the cloth in a manner that shows the placement of stitches thereon. A spacer bar is provided adjacent the wheel for spacing the wheel a precise distance from the edge of the material. The marking means includes a well and, in an alternative embodiment, may include ink or chalk cartridges placed therein for providing the ink or chalk to the wheel. The handle is angled from the stem such that it provides an easy operation of the pointed wheel across the cloth.

Abstract: Disclosed are a method and apparatus for marking beams for the placement of studs, rafters and joists. The invention uses three instruments for measuring, aligning and marking. The first and simplest instrument is a tee-square instrument which requires independent measuring to determine the desired framing position. At the desired position, ink pads are pressed against the beam to mark the location. The ink pads protrude from a blotter head assembly which releasably attaches through a neck to a refillable ink cartridge. Single center distances of regular and uniform spacing are marked with an instrument having blotter head assemblies removably mounted through the periphery of a wheel at even fractions of the circumference. The wheel is rotably mounted on an axle to which a handle is attached and the wheel has gripping teats which insure the accurate translation from circumferential to linear distances.

Abstract: A scale printing instrument wherein one or more printing toothed wheels are rotatably held by a tip end of a grip member, an arm is carried by said grip and a brush containing a printing composition such as ink is provided at a tip end of said arm. With this instrument, when the wheel or wheels are run on paper while keeping the wheel or wheels in contact with the paper, the ink is furnished to the toothed wheel to print a scale having given intervals on the paper.
